Opto22 SNAP-IAC-A-16

SNAP-IAC-A-16 SNAP isolated 16-pt digital input module, 180-280 VAC/VDC

The SNAP-IAC-A-16 senses on/off status for 16 channels of 180-240 VAC/VDC input. The module features automatic
counting and latching.
 
For field wiring, use the SNAP-ACF6 wiring harness assembly with flying leads.
 
Part of the SNAP PAC System, the module mounts on a SNAP PAC rack with a SNAP PAC brain or rack-mounted
controller. Analog, digital, and serial I/O modules can all be on the same rack. Such an I/O unit is also well suited for PC-
based control or for use as intelligent remote I/O for an Allen-Bradley MicroLogix or other RSLogix-based PLC system,
such as ControlLogix or CompactLogix.
 
The SNAP-IAC-A-16 cannot be used with legacy brains.
