■ Description
■ Special Features
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.
■
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 analog outputs in an 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
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 (open-drain) 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).
Approvals CE marked. UL, cUL listed Class I; Division 2; Groups A, B, C, D.
