Description
Analog output module supports two channels with voltage or current loop modes. The channel mode is WEB interface configurable. The available choices are – 0-20mA, 4-20mA, 0-24mA, 0-5V and 0-10V. Both channels have 12-bit resolution.
The device has 4 open drain outputs. All they are configurable either as standard digital outputs (On/Off) or as PWM outputs. In PWM mode, the outputs supply up to 2000Hz with 10-bit resolution.
Analog outputs and open drain outputs are galvanically isolated from the module’s power supply. The isolation between the two parts is 1000VDC.
The module has also 2 relays with normally open and normally closed contacts. The relays can be activated either through the WEB interface or through some of the supported M2M protocols – SNMP, HTTP API, and MODBUS TCP/IP.
The device supports an advanced schedule functionality. The four schedules can be used for single (one-time) or repetitive (weekly) tasks. The resolution of the time period is 100mS. The embedded RTC (real-time clock) together with time server synchronization ensures high accuracy when executing the scheduled tasks. The schedules can activate automatically either relays or open drain outputs.
