I/O and terminal bocks appear healthy

This month’s roundup on I/O and terminal blocks demonstrates that the industry seems to be recuperating, product development money is flowing, and companies are getting competitive again.

Unnamed, low-profile, M12 eurofast junction boxes provide quick-disconnect wiring. Available in 4 or 8-port with single or dual output, they offer multiple home-run connector and integral cable options. Home-run connectors can be mounted on the top or side of the housing. Integral cables with a 12-pin, 1 1/8-16 UN minifast connectors also are available for single-output junction boxes. Turck; 800/544-7769; www.turck.com

Adam-4150 digital I/O module has seven input channels and eight output channels with over-current/short-circuit protection. It has 1 kV surge protection on power inputs, 3 kV EFT, 8 kV ESD protection, power input range of approximately 10 to 48 VDC, an LED display to monitor the status of the address settings, a digital filter function, digital output support pulse function, and Modbus RTU protocol.

Type i2P-100 electro-pneumatic transducer converts mA input signals to a switch-selectable proportional pneumatic output signal. The transducer has ATEX certification for intrinsic safety (Zone EEx ia IIC T3/T4/T5), flameproof (Zone EEx d IIC T5/T6), and Type N (Zone EEx nC IIC T5/T6). It allows users to select and mark protection methods at installation. More info at controlglobal.com. Fisher Controls; 641/754-3288; www.EmersonProcess.com

831 Series DC/DC converter uses a ceramic base and hybrid technology to eliminate any external heat sink requirements, which reduces the overall installed cost of the device. All the device requires is two external capacitors. It’s packaged in a small, space-saving, hybrid SIP configuration (1x0.5x0.225 in.) that minimizes PC board footprint.

SCM5B48 isolated and field-configurable accelerometer input module provides excitation to piezoelectric sensors with built-in microelectronic amplifiers. The module provides a constant current excitation to the sensor, then isolates, filters, and amplifies the sensor output, yielding a high-level analog voltage output. The excitation current, signal gain, and filter high-pass and low-pass cutoff frequencies are field-configurable through a set of slide switches. More info at controlglobal.com.

Unnamed IEC terminal blocks meet the specifications and requirements of applicable UL, CSA, and IEC standards and are rated for Code 1, factory wiring only, and Code 2, both factory and field wiring. A screw clamp is available from 20A to 232A, and a spring clamp from 20A to 50A. Miniature panel mount is also available from 20A to 35A, in both spring and screw clamp.

Unnamed terminal blocks are identical equivalents to the Allen-Bradley 1492J series, Phoenix Contact UKN series, and Weidmuller WDU series. The color of the housings is the same, so there are no visual differences. The metal clamping bodies are made of a nickel-plated copper alloy, screws are plated to prevent corrosion, and all materials are ROHS compliant. More info at controlglobal.com.

KS series bus terminals enable complete wiring to be removed as a plug connector from the face of the I/O housing without needing tools. The connector can be removed from the bus terminal assembly by pressing an unlocking tab. Users insert the new I/O component and re-plug the connector in with the wiring. This reduces installation time and the risk of wiring errors. More info at controlglobal.com. Beckhoff Automation; 952-890-0000; www.beckhoffautomation.com

Snap-AITM-8 thermocouple input module accepts up to eight channels of temperature or millivolt input from a variety of standard thermocouples, or from any -75 to +75 millivolt device input. It can also be configured to accept millivolt readings in the -75 to +75 range directly from Wheatstone bridges, strain gauges, and other instruments and devices. More info at controlglobal.com.

P Series terminal blocks with push-in connections are safe, easy to use, and can reduce wiring time by as much as 60%. Models PDU 2.5/4, PDU 6/10 and PDU 16 have wiring ranges of 20–10 AWG, 14–8 AWG, and 14–4 AWG, respectively. More info at controlglobal.com. Weidmuller; 804/794-2877;  www.weidmuller.com

UT 4 double-level terminal blocks can connect conductor cross-section ranges of 0.14mm2 to 4 mm2 (26-10 AWG). The four-conductor connection saves space compared to the company’s standard, feed-through terminal blocks.  Bridging from the upper level to the lower level is available, and ZB6 or ZBFT6 marking material can be used as terminal block markers on both levels.
