PC/104 20 Opto-Isolated input with 20 Relay Outputs
IR104-PBF is a high-density PC/104 format digital I/O module designed for industrial applications requiring isolation between the computer and the external signals it is monitoring and controlling. This module features 20 opto-isolated digital inputs and 20 relay outputs. Each input can accept both AC and DC voltages as low as 3V and as high as 24V.
The opto-coupler inputs are located on a pin header at the top of the board, while the relays feature quick-disconnect terminal blocks (10 relays per block) that accept wire ranging from 14-28AWG. The board will operate in ambient temperatures ranging from -25 to +70C.
The 20 relay outputs have SPST (form A) normally open contacts. Each relay can switch both AC and DC voltages. The relays have long lifetime (20,000,000 operations, 100,000 at full load) and quick actuation time (6ms max operate, 3ms release). Maximum load is 5A @30VDC. Relay connections are made with detachable screw terminal blocks. Each of the 2 blocks carries contacts for 10 relays.
The 20 opto-isolators can accept either AC or DC inputs ranging from 3V to 24V. Opto input connections are made with a 40-pin pin header that mates with standard ribbon cables.
