- The 50A55-843 is an automatic gas interrupted ignition control that employs a microprocessor to continually monitor, analyze, and control the proper operation of the gas burner, inducer, and fan. Signals interpreted during continual surveillance of the thermo-stat and flame sensing element initiate automatic ignition of the burner, sensing of the flame, and system shut-off during normal operation.
- Input Voltage: 25 VAC 50/60 Hz. Max. Input Current @ 25 VAC: 0.45 amp. Relay Load Ratings: Valve Relay:1.5 amp @ 25 VAC 50/60 Hz 0.6 pf .Ignitor Relay:6.0 amp @ 120 VAC 50/60 Hz (resistive). Inducer Relay:2.2 FLA–3.5 LRA @ 120 VAC. Circulator Relay:14.5 FLA–25.0 LRA @ 120 VAC.
- The 50A55 has only one serviceable part–an automotive type fuse, which protects the low voltage trans-former from damage if its output is short-circuited. If the fuse has opened up, remove whatever caused the short circuit and replace the fuse with only a 3 Amp automotive type fuse. If the fuse is not the cause of the control's problem, replace the entire 50A55 control. There are no other user serviceable parts.
- Superior Quality, advanced microprocessor-based high-precision PCB manufacturing, soldering and assembly technology, professional tests to ensure optimal performance and long-lasting reliability.
