ABB PM851AK01 3BSE066485R1 processor module

The 16–Channel Analog Current Input module, IC694ALG223, provides 16 single–ended inputs. Each input can be configured using the configuration software for any of three input ranges: ▪ 4 to 20 mA ▪ 0 to 20 mA ▪ 4 to 20 mA Enhanced High and Low alarm limits are available on all ranges. In the 4 to 20 mA Enhanced range, a low alarm limit can be set up to detect input current from 4 mA to 0 mA, providing open-wire fault detection in 4 to 20 mA applications. The module also reports module status and external power supply status to the CPU using its assigned program reference addresses. This module can be installed in any I/O slot in an RX3i system.

The MODULE OK LED provides module status information on power–up as follows: 

▪ ON: status is OK, module configured; 

▪ OFF: no backplane power or software not running (watchdog timer timed out); 

▪ Continuous rapid flashing: configuration data not received from CPU;

▪ Slow flashes, then OFF: failed power–up diagnostics or encountered code execution error. The User Supply LED indicates that the external 24 VDC supply is within specifications.

Module Power 

This module consumes 120 mA from the 5 VDC bus on the PLC backplane. It also requires 65 mA plus current loop current(s) from a usersupplied +24 VDC supply.The number of channels to be scanned. Channels are scanned in sequential, contiguous order. Reference Address for Input Data The memory location for input data from the module. Each channel provides 16 bits of analog input data to the PLC CPU.

The memory location for where status information from the module starts.
