SIXNET ET.GT.ST 16-channel DC Discrete Output Module

Product Description

SIXNET ET.GT.ST is a high‑density 16‑channel DC discrete output module of SixTRAK series (Sixnet, part of Red Lion, USA). It adopts plug‑in ST‑BUS backplane bus architecture and requires matching wiring base. Serving as output unit for SixTRAK RTU / distributed I/O system, it provides 10‑32 VDC digital switching signals to drive field relays, indicator lamps, solenoid valves and other DC field actuators.

1200 V galvanic isolation between channels and system bus suppresses field‑side fault interference. Built‑in surge suppression clamps inductive‑load reverse voltage for channel protection. Channel 1 can be configured as watchdog output. Per‑channel LED status indicators show ON/OFF status. Designed for wide‑temperature industrial environment with good vibration and EMI resistance. OEM discontinued. Surplus‑new and tested‑refurbished units act as critical spares for oil‑gas, water‑treatment and distributed RTU system maintenance & I/O expansion.

3. Product Application

Working with SixTRAK RTU / I/O racks, ST‑DO‑DC2‑16 outputs discrete signals to control field actuators. Main application fields are listed below:

1. Oil‑gas Pipeline Transmission: RTU valve‑chamber control for driving solenoid valves, field relays and status lamps.
2. Water‑treatment Industry: Distributed automation stations for wastewater & clean‑water plants, logic output for valves and pump auxiliary relays.
3. Oil‑gas Gathering Sites: Remote RTU systems for process interlock and discrete control of field equipment.
4. Factory Automation: Distributed I/O for packaged machinery, driving small relays, indicator lights and 24 VDC solenoid valves.
5. Utility Energy Projects: Remote supervision systems for pumping & compressor stations, on‑site actuator switching control.
6. Legacy‑system Maintenance & Retrofit: Replacement for failed SixTRAK I/O modules, digital output point expansion for existing RTU installations.
