Functional engineering application
The Pixsys DRR244-13ABC-T represents the highest automation specification in the Pixsys Blue Line DIN-rail instrumentation portfolio. Built in a robust 4-module DIN 43880 format (71 × 90 × 64 mm) with a V0 polycarbonate enclosure and self-extinguishing silicone front interface, the DRR244 combines high-density I/O with standard RS485 Modbus RTU networking, making it the ideal distributed process node for multi-zone heating and industrial SCADA integration. The front faceplate includes a high-contrast two-color LED display: 4 white digits of 0.5" height for Process Variable (PV) and 5 red digits of 0.3" height for Setpoint (SP) and alarm visualization. The universal 16-bit analog input digitizes thermocouples (K, S, R, J, T, N, B with cold junction compensation across -25..85 °C), RTDs (Pt100, Pt500, Pt1000, Ni100, PTC 1k, NTC 10k), linear signals (0/4..20 mA, 0..10 V, 0..60 mV), and potentiometers up to 150 kΩ at programmable speeds down to 2.1 ms. Process control outputs are comprehensive: an isolated analog output selectable for 4..20 mA or 0..10 V DC (40,000 points resolution) provides continuous proportional control to modulating steam control valves or SCR power thyristors, or serves as an analog PV/SP retransmission channel. A dedicated 50 mA Current Transformer (TA) input monitors heating element current in real time, triggering immediate Loop Break Alarms if an element fails. Discrete outputs include three electromechanical relays (two rated 5 A and one rated 2 A @ 250 V AC) and two digital SSR drive outputs (12/24 V DC, 30 mA max). Connectivity is standard: a galvanically isolated RS485 serial port operates on Modbus RTU from 1200 to 115200 Baud, allowing multiple DRR244 modules on the same DIN rail to be daisy-chained to a master PLC, SCADA system, or IIoT cloud modem. Mobile configuration via the MyPixsys smartphone app (NFC) and PC configuration via the front Micro-USB port provide rapid parameter cloning. The switching power supply accepts 24..230 V AC/DC (±10%) with 2.5 kV galvanic isolation.
Advanced 4-module DIN-rail process controller with RS485 Modbus RTU standard, 4-20mA / 0-10V analog output, Current Transformer (CT) input, 3 relays, 2 SSRs, and NFC.

Common questions on this part
Yes. The DRR244-13ABC-T model comes with galvanically isolated RS485 Modbus RTU serial communication standard. It supports baud rates from 1200 up to 115200 Baud, enabling direct networking with PLCs, SCADA touchscreens, and industrial IoT modems.
Yes. The DRR244 features an isolated analog output configurable in software for either 4..20 mA or 0..10 V DC (40,000-point resolution, ±0.2% F.S.). It can drive proportional pneumatic valve positioners, electric modulating valve actuators, or SCR power controllers.
The 50mA CT input continuously measures load current flowing to electric heating elements during active heating cycles. If an element burns out or circuit breaker trips, the controller detects the drop in current and activates a Loop Break Alarm contact, preventing undetected batch cooling.
The DRR244 provides three electromechanical relays (two 5 A contacts and one 2 A contact @ 250 V AC) and two digital SSR drive outputs (12/24 V DC, 30 mA max), allowing simultaneous multi-stage heating, cooling, and safety alarm interlocking.
