Option Description: Remote setpoints use either voltage or current inputs, depending on the specified option:
Option -DIC: Switch Input Closed
Option -RSP4: 0-5 Vdc
Option -RSP5: 1-5 Vdc
Option -RSP6: 0-20 mA
Option -RSP7: 4-20 mA
The input signal is scalable in the Remote Analog Setpoint Menu. Activation of the analog setpoint causes the F1
indicator to illuminate. For current (mA) options, the input resistance is 255 ohms. For voltage input options, the
input resistance is greater than 10K ohms.
Note: Switch input option -DIC is active when switch is closed. The digital
input option menu controls the programming of this switch.
*Ground shield at one end, taking care not to run wires next to power circuitry. Maximum length will be determined
by noise performance.

Options -PVSV1, -PVSV2: Process Output
Option Description: The Setpoint Variable or Process Variable is transmitted to a remote device (chart recorders,
indicators, data recorders, computers, process controllers, etc.) with 1 of 2 different interfaces:
Option -PVSV1: 4-20 mA
Option -PVSV2: 0-5 V
The output signal is scalable in the Auxiliary Output Menu. Multiple remote indicators may be driven by the controller.
For current (mA) options, the remote indicators are connected in series. The sum of the input resistance for all
remote indicators must be less than 400 ohms. For voltage options, the remote indicators are connected in parallel.
The sum of the currents for all remote indicators must be less than 10 mA.
