I/O Systems

Product roundup: I/O and terminal blocks

These workhorse modules are gaining modularity, safety, programmability and other surprising features.

Four-port serial I/O in chassis

Opto22 GRV CSERI 4GRV-CSERI-4 groov serial I/O module plugs into a groov Edge Programmable Industrial Controller (EPIC) chassis alongside the new groov EPIC and discrete and analog I/O modules; enables EPIC to add communication with RS-232 and RS-485 serial devices; and provides the right mix of analog, discrete and serial signals needed at any location. GRV-CSERI-4 has four, independent, isolated serial ports, supports baud rates up to 1 Mbps, and runs from -20 to 70 °C (-40 to 85 °F) and humidity (non-condensing) of 5-95%.

33 Devices appear as one

Turck BEEPBackplane Ethernet Extension Protocol (BEEP) has been integrated into many of Turck's multiprotocol digital block I/O modules. BEEP allows a network of up to 33 devices (one master and 32 slaves) or 480 bytes of data to appear to the PLC as one device on one connection using one IP address. BEEP also supports drop-in device replacement, reducing downtime and costs. If the network is set up using BEEP, technicians can simply replace a slave device with a new device to keep the system online.

Intrinsic, functional safety combined

Beckhoff ELC EtherCAT IO modulesELX compact EtherCAT I/O modules have added analog input terminals with TwinSAFE SC (single-channel) technology. These I/O are available as 12-mm-wide modules with two or four analog input channels for 4-20 mA. A single-channel terminal directly connects intrinsically safe (IS) incremental encoders, which evaluate a diagnostic NAMUR signal. ELX complies with ATEX and IECEx, and enables direct connection of intrinsically safe (IS) field devices through to Zone 0/20 based on an integrated safety barrier.

3 Configurations in one 

ABB DBL distribution blocksDBL distribution blocks offer three configurations in one product: single-pole splitter, multi-pole splitter and grouping functionality. They're modular and touch-proof, and save up to 50% on rail space. DBLs are available in five sizes from 80-400 A, and can be easily ganged together for multi-pole applications. They can be mounted on traditional, 35-mm DIN rails or directly on panels. DBL is ULrecognized, offers high flammability resistance (UL94-V0 rating), and carries a 100 kA SCCR rating (UL 1059/UL 508-A standard).

Fast connectivity, expanded bandwith

Rockwell Flex 5000 IO modulesFlex 5000 I/O modules are built on a 1-Gigabit architecture with communications supporting device level ring (DLR), linear and star topologies. They're designed to operate at -40 °C to 70 °C, and their flexible architecture includes vertical and horizontal mounting, and copper and fiber media options. Removal and insertion under power (RIUP) allows replacement of existing I/O, and online change capability allows configuration of new I/O, both while the system continues to run.

EtherCAT remote I/O for DCS

Advantech Amax 4800 EtherCAT slave modulesAmax-4800 industrial EtherCAT slave modules are compact and have an integrated DIN-rail mount kit for a Euro-type, pluggable terminal block with an LED indicator. They're protected by an isolation circuit, have a high-density channel design for DCSs, and support I/O formats such as isolated digital input, isolated digital output, photoMOS relay output and relay contact. An analog input module and an output module are available for data acquisition and device control.

Modular power blocks save time

PhoenixContact PTFIX potential distribution blocksPTFIX potential distribution blocks have direct connections and a modular, tool-less design. They offer 11 color options and mounting options include horizontal and transverse positioning on 35-mm DIN rail; standard horizontal on NS 15 “mini” DIN rail; direct with flanges; and tool-free, adhesive. PTFIX's minimal footprint saves up to 50% space in cabinets. PTFIX is available in 2, 6, 12 and 18 terminal point options in 1.5-, 2.5-, 4-mm2, 2.5 mm2 with a 6 mm2 feed-in, and 4 mm2 with a 10 mm2 feed-in.

Lever-actuated PCB connector

Wago MCS Maxi 832 SeriesMCS Maxi 832 Series is reported to be the world’s first, lever-actuated PCB connector for high-power applications up to 66 A/600 V and up to 4 AWG conductors. These touch-proof connectors feature low mating forces, yet high contact forces. They also have flexible coding for quick coding changes even after installation. MCS MAXI 832 claims to offer the only completely tool-free, in-hand wiring solution for wire sizes 18 to 4 AWG. They also feature wire-to-board and wire-to-wire configurations in two- to six-pole variants.

Compatible clips and couplers 

Weintek iR series IO modulesiR Series I/O modules use couplers that support Modbus TCP/IP and CANopen to create a modularized system that's compatible with most control systems. A patented fixture clip also makes it easy to connect to many I/O modules. iR also has a screw-less design and a flexible module assembly to avoid unnecessary nodes, while its patented iBus has strong noise resistance and efficient communications, enabling I/O status updates in milliseconds, even of more than 10 modules are used.
