Jerome 631-X instruments shipped after early 1995, are capable of providing 0-2 volts analog output. Instruments shipped before that time can be upgraded by a firmware update and adjustment.
Instruments that are capable of 0-2 volt output can be upgraded to the 4-20 mA output with the addition of an option board upgrade. This must be installed at the factory.
Connection and Setup:
•0-2 volt devices connect as shown in Figure 1. If the instrument includes an option board, be sure its analog jumper (SW101) is set to the “V” position.
•The 4-20 mA active receivers connect as shown in Figure 2. The active receiver must contain a voltage source to power the loop current. The receiver must also have an isolated input circuit. That is, it must not be connected to ground or to a voltage source referenced to ground. Be sure that jumper SW101 is set to the “I” position before power is applied.
