32-CHANNEL ANALOG INPUT MODULEAcromag's ES1253 32-channel analog input model converts 16 DC current and 16 DC voltage single-ended analog inputs from various transducers and instruments for transmission to an Ethernet-based control network. A DB25 serial port provides an alternative voltage input connection from a rack of 7B or 8B signal conditioning modules to monitor a wider variety of sensors including temperature, frequency and load cells. Modbus TCP/IP and UDP/IP protocol communication, as well as peer-to-peer messaging, are supported. Units are available in several configurations starting at $1,550.
