4 analog output channels
0 to 20mA or 0 to 10V DC output range
4 discrete output channels, open drain MOSFETS (1A DC loads, 0 to 35V DC)
10 to 36V DC, 24V AC power
Modbus RTU high-speed RS-485
These modules drive four analog output channels and also feature four discrete outputs for on/off control. Isolation separates the output, power, and network circuits.
Network communication adheres to the industry-standard RS-485 Modbus RTU protocol. AC and DC power sources are supported with nonpolarized, diode-coupled terminals.
The analog outputs generate a signal based on communication from the host. They accommodate wide DC voltage or current ranges. Discrete outputs provide simple on/off switching capability for external devices.
Combining analog outputs, on/off controllers, and a network interface in a single package, makes this instrument extremely powerful. Multi-channel design adds cost-efficiency and allows high-density mounting.
Plus, safe, rugged construction make it reliable for both control room and distributed field I/O use in a broad range of temperature control applications. Custom module configurations are also possible (consult factory for details).
Features
Standard Modbus RTU protocol with high-speed RS-485 communication (up to 115K bps)
12-bit D/A yields 0.1% of span resolution and accuracy
Four outputs in a single inch-wide module reduces system costs and saves panel space
Four discrete outputs enable host-controlled on/off switching
Heavy-duty 1A solid-state relays provide dependable on/off control of industrial devices
Self-calibration lowers maintenance costs by reducing periodic manual calibration checks
Watchdog timers provide a configurable failsafe output state for use when host I/O communication is lost
Three-way isolation eliminates potential ground loops between power, output and network circuitry
Self-diagnostics monitor microcontroller activity to detect operational failures (lock-up) and execute a reset to restore communication
Operating temperature: -25°C to +60°C (-13°F to +140°F), limit 917MB ambient to 50°C maximum for supply voltages less than 15V
