Interposing relay Panel | Automation & Control Engineering Forum
Dear Summit, Normally the DO of DCS/PLC are operated by Open collector output of Transistor or TRIAC i.e. TTL logic based on microprocessor. Thus it is not recommended to make relay continuously energised for the long time.To achieve this, a logic is prepared such that a Relay coil (24V) is being energised for moment (2 Sec) in control panel
Interposing relays | PLCS
Interposing relays were seen as a luxury as they took up too much space, extra wiring, and added cost. Nowadays, PLC''s/PAC''s, cards/modules and relays have become smaller, reducing their footprint in an installation and lessons have been learned on the hazards of not protecting or isolating outputs (or inputs for that matter).

Interposing Relays: What Are They?
How Interposing Relays Work. Interposing relays operate by receiving a low-power signal from a control device, such as a PLC, and using it to control the switching of a higher-powered load. When the low-power signal is
Wiring diagram for interposing relay panel
The relays in an interposing relay panel are wired according to a specific wiring diagram, which outlines the connections between the control signals, the relays, and the power circuits. This ensures that the correct signals are sent to the appropriate devices and that the devices are activated or deactivated in the correct sequence and timing.
