Pneumatic indicator relay 2400M, 4400M

The 2400M and 4400M Space Saving Indicating Relays are used in failsafe pneumatic or hydro mechanical control systems. The indicating relays are used in panel systems and sequencing systems and are used to indicate the status of process operating conditions. Normally, an indicating relay is connected to each condition sensing device in a system. The condition sensing devices measure process temperature, pressure, speed, vibration, etc. When in a safe condition, the indicator will show a green indicator. The indicating relays can be linked together to provide first out indication in a system.
