About 1771-IC

The AB 1771-IC is a digital input module in the 1771 Series of Digital I/O Modules used in the assembly of PLC-5 Systems. It features input filtering that limits and suppresses the effects of voltage transients caused by electrical noise and/or contact bounce. This decreases the occurrence of electrically-related downtime, and doubles or triples product life. Plus, this DC module is shipped in a static-shield bag for protection against electrostatic discharge.

The 1771-IC Digital DC Input is a sink-type (source load) module with a 10-60V DC voltage category and total of 8 inputs. It receives power via the 1771 I/O backplane from the power supply and it has a 42-56V DC operating voltage range. It requires a 74mA backplane current load from the supply’s output. Its maximum off-state current is 3.7 mA. Due to input filtering, it has a typical signal delay of 17 (±7) ms when turned on and of 20 (±7) ms when turned off.

The 1771-IC Module works with 2 and 3–wire devices including DC proximity switches, limit switches, float switches, pushbuttons, photoelectric sensors, and selector switches. For 3-wire applications, the off-state leakage should not exceed 4mA. It uses wiring arm with catalog number 1771-WA.
