Digital Input Module (Modbus Rtu) Dl7-In2Rs485; The Two-State Outputs Module Dl7-Out6Rl; Analogue Outputs Module Dl7-Out3 - Metronic DL7 Series User Manual


2 independent RS485 ports galvanically separated,

each input has a separate four-pole terminal block,

24 VDC (max 200 mA) output for powering external transducers,

a two-colour LED diode informing about the module's operating status.

5.11 Digital Input Module (Modbus RTU) DL7-IN2RS485


designed to work with instruments and sensors that communicate with the RS-485 bus
according to the Modbus RTU protocol,

Possibility of reading and recording up to 25 digital values,

2 independent RS485 ports galvanically separated,

each input has a separate four-pole terminal block,

a two-colour LED diode informing about the module's operating status.

5.12 The two-state outputs module DL7-OUT6RL

 6 outputs galvanically separated from each other and the remaining circuits,
 output types - semiconducting output relays (SSR) AC/DC rated at 0.5 A,
 each input has a separate pin type four-wire terminal block,
 a two-colour LED diode informing about the module's operating status.

5.13 Analogue outputs module DL7-OUT3

 3 galvanically separated channels of analogue outputs, each can work as a power source
or a voltage source in the following ranges:
 0-20 mA (active power source),
 4-20 mA (active power source),
 0-24 mA (active power source),
 0-5 V (voltage source),
 0-10 V (voltage source).
 Program mode selected, each channel can be configured to work in a different mode and
range,
 Each channel has two connectors for connecting the receiver, one is for connecting the
current loop receiver, the other one for the voltage receiver, there is no possible to use
both: current and voltage source for a given channel at the same time,
 Analogue output is based on a specialized A/D converter with a resolution of 12 bits.
