ACCEPTABLE SUPPLY VOLTAGES AND LOADS FOR EXCELA
The charts below provide a range of acceptable power supply voltages (in Volts) and series loads (in Ohms).
NOTE:
If you need assistance with determining the compatibility of the Excela electronic switch with your PLC, DCS, or relay, we
can help. Please have the manufacturer’s model number of the PLC, DCS or the relay ready when you call. Please call (617) 923-
6977 (Technical Sales) for assistance.
*De-rate 0.001A per C above 25°C
**
At -40°F/°C start up current could be up to 3 mA
TROUBLESHOOTING
Excela is an electronic switch and cannot be properly tested with an ohmmeter. Instead, measure the voltage drop across the
switch connected to the terminal block. A properly functioning Excela electronic switch will exhibit the following voltage levels:
Model
Voltage when switch is open
Voltage when switch is closed
1GSWLL
8-50 VDC
5 VDC
DISPLAY MODULE CALIBRATION
The Serial # on the module and the enclosure must match for proper operation. Swapping modules among similar ranges
would result in the product calibration being outside the stated tolerances.
