Good Morning
I have a temperature controller made by HBO Instruments, model #HBO 442.03X, serial # 960429-1 with the following specs.
Mode: on / off
Voltage: 230 V AC
Range: 0-100, 0 degrees C
Input: Pt 100 ; SP pot.m.
Output: 3 x relay, 0-4 V = 0-100 degrees C
Made for Skov & Weidemann
I am looking for an exact replacement ( panel cutout size and electrical connections) as a backup unit
