10-3. OP-24 RS-232C serial interface and Comparator relay output
The OP-24 has an RS-232C series interface and relay output for the comparator
function. It allows output of the HI, OK or LO signal results to an external device as a
solid state relay output.
The specification for the RS-232C interface is same as the OP-23 (FG-23). See
“10-2. OP-23 RS-232C serial interface” for further information.
Interface specifications
Pin connections
Maximum rating for relay is as follows.
? Maximum voltage: 50V DC
? Maximum current: 100mA DC
? Maximum ON resistance: 35?
(Inside of OP-24)
Mating connector:
DIN 8 pin (JA+TCP058)
