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.

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.
