TCW280 Analog Output Module

With voltage or current loop modes, the analog output module provides two channels. The Web interface allows for channel mode customization. There are six options: 0-20 mA, 4-20 mA, 0-24 mA, 0-5 v, and 0-10 v. There is 12-bit resolution for both channels.
There are four open drain outputs on the device. All of them can be set up as PWM outputs or as regular digital outputs (on/off). The outputs in PWM mode can deliver up to 2000 Hz at 10-bit resolution.

The power supply of the module is galvanically insulated from analog outputs and open drain outputs. 1000 VDC of isolation separates the two components.

Two relays with typically open and normally closed contacts are also included in the module. The Web interface and a few M2M protocols, including SNMP, HTTP API, and MODBUS TCP/IP, can be used to activate relays.
The gadget has sophisticated scheduling capabilities. The four schedules can be used for one-time or recurring tasks that need to be completed every week. The time period has a resolution of 100 mS.The embedded RTC (real-time clock) and time server synchronization guarantee high accuracy when the planned tasks are carried out. Relays or open drain outputs can both be automatically activated by the schedules.

Features:

• Two 12-bit resolution analog voltage or current loop outputs;
• 4 outputs with open drains that support ON/OFF and PWM;
• Two relays with contacts that open and close normally;
