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).

6 FAQs about [Sudan interposing relay cabinet]
What is an interposing Relay Cabinet?
An interposing relay cabinet is a device used along with automation devices to control heavy load circuits like AC and refrigerators. It has auto/manual switches to bypass the loads from automation controls and provides feedback of switch positions to the control panels.
What is an IPR cabinet?
Interposing Relay (IPR) cabinet is used in industrial automation systems along with automation devices for proper controlling of load circuits such as Electrical feeder contactors for motors & compressors, Air Conditioning systems, Lamps, Fans, etc. It can be used to control light circuits and AC circuits.
What is an interposing relay?
Interposing relays can ‘change’ a control (coil) voltage circuit into a higher or lower load voltage. Interposing relays can use a small control (coil) current and translate it into a substantially higher load current that would damage the sensitive digital controls.
What are interposing relay panels in industrial control?
Interposing relay panels in industrial control are used to communicate the signals and status between the Automation system such as DCS & PLC and electrical modules in Machine control centre (MCC) such as motor control units, motors, pumps, lamps, and so on.
What is a relay used to interpose between mismatched devices?
