Functionality

Interface RS485, CS31 protocol
Address switches For setting the module’s address (00d to 99d)
Digital inputs 8 (24 VDC; delay time configurable via software)
Configurable digital inputs/outputs 8 (24 VDC, 0.5 A max.)
Analog inputs 4 (configurable via software), resolution 12 bits plus sign, voltage, current and RTD input
Analog outputs 2 (configurable via software), resolution 12 bits plus sign, voltage and current output
Fast Counter Integrated, many configurable operating modes
LED displays For system displays, signal statuses, errors and power supply
External supply voltage Via terminals UP and ZP (process supply voltage 24 VDC)
Effect of incorrect input terminal connection Wrong or no signal detected, no damage up to 35 V
Required terminal unit TU551-CS31 or TU552-CS31 TU551-CS31 and TU552-CS31 for CS31 Communication Interface Modules
