Product Details:

MODICON AS-B808-016 is a 16-point triac type discrete AC output module belonging to the classic Modicon 800 series I/O family, originally released by Gould Modicon. It receives output instructions transmitted from the host PLC CPU and drives AC field loads such as indicator lamps, auxiliary AC relays, small solenoid valves and local alarm buzzers through triac switching circuits. The output channels are divided into two independent groups with eight points per group, designed for 230 Vac field load supply with wide voltage tolerance. Each channel integrates transient voltage suppression and overcurrent protection to protect the module against surge spikes and accidental load short-circuit in field circuits. This module adopts standard rack mounting and can be plugged directly into the Modicon 800 I/O backplane. Every output channel is equipped with an individual LED indicator to visually display the on or off switching state for quick site inspection. As an obsolete original spare part, it is mainly used for maintenance and retrofit of legacy Modicon distributed automation systems. Direct replacement retains the existing field wiring, terminal arrangement and rack configuration, reduces field modification workload and helps shorten production downtime.
