Honeywell RM7895C1012

The On-Off Primary Control With Prepurge by Honeywell operates on a 120 VAC, suitable for both 50 and 60 Hz frequencies. This model, employing an interrupted pilot type, guarantees a 10-second main flame and a 4 to 10-second pilot flame establishing period. It is specifically designed to function with the 7800 Series Amplifiers and employs a delayed main valve.

This advanced system features automatic burner sequencing, flame supervision, system status indication, as well as system or self-diagnostic ability and troubleshooting for smooth operation and easy maintenance. To ensure the device's full functionality, a subbase, amplifier, and prepurge timer are mandatory.

For extra convenience, several options are available. These include a Modbus interface, a keyboard display module, a remote display module, and a first-out expanded annunciator. The device’s current operational sequence can be visualized through five LEDs, while operational and fault information can be announced either locally or remotely with the aid of the optional S7800 Keyboard Display module.

The device also offers interchangeable plug-in amplifiers and a non-volatile memory, which securely retains history files and lockout status even after loss of power. Further, it gives the user the option to select relight or lockout in case of loss of flame.

With an operational temperature range from -40 F to 140 F, this On-Off Primary Control With Prepurge is designed for tough industrial environments and varied applications. Whether you're looking for enhanced operational control or efficient automation, this Honeywell product delivers superior performance every time.
