TB-24R
24 Relay Outputs Termination Board
12 V and 24 V Coil Voltage Available !


Description

The TB-24R relay output termination board is designed for industrial control applications. It contains 24 electro-mechanical SPDT relays which can be driven by the 24-bit digital output ports of the ACL-7122, ACL-7124 and PET-48DIO.

Each relay's switching capacity is 60 W / 125 V. The normally open, normally closed and common contacts for each relay are made available for maximum flexibility.
