Introduction

MODEL: SC / L - 1501 / DPC 965M

The DPC 965M is a compact and reliable microcontrollerbased process indicator and controller. It is designed to display process variables directly from a standard 4–20 mA DC loop without requiring any external power supply, while also offering versatile control and communication features

Application

Designed for indication and control applications in industrial processes
Large 7-segment Red LED display ensures visibility from long distances.
4½ digit resolution provides high accuracy of ±0.3% ±1LSD.
Accepts 4-20 mA DC linear input the most widely used signal in process industries

Features

Rugged, state-of-the-art microcontroller-based design.
4½ digit, ½-inch LED display for clear process value indication.
Field-settable flow totalizing and rate display.
Signal retransmission capability.
Programmable hysteresis for two or four relays.
User-configurable span for flexible scaling.
RS-485 serial communication with Modbus RTU protocol.
Fully compatible with SCADA and DCS applications.

Optional

Two / four relays with individually settable set points and hysteresis.
RS-485 port with Modbus RTU for integration with all standard
SCADA/DCS systems.
4–20 mA retransmission output for remote display or PLC connectivity.
