MB-LI-4 Hi
Pulse counter,
4-channel,
with Modbus RTU output
Do not dispose of this device in the trash along with other waste! According
to the Law on Waste, electro coming from households free of chage and
can give any amount to up to that end point of collec� on, as well as to sto-
re the occasion of the purchase of new equipment (in accordance with the
principle of old-for-new, regardless of brand). Electro thrown in the trash or
abandoned in nature, pose a threat to the environment and human health.
Purpose
The MB-LI-4 pulse counter is used for counting the AC/DC signals
generated by external devices to determine the number of com-
pleted work cycles and for exchanging the data via RS-485 port
in accordance with the Modbus RTU protocol.
Functions
» 4 independent counters;
» Counter input designed to work with AC/DC signals 160÷265 V;
» Factor adjustment (a floating-point value);
» Rescaled value (Number of pulses × factor);
» Selecting a mode of state 1 trigger: high or low voltage;
» Selecting an input pulse edge (leading or trailing);
» Frequency filter that allows you to limit the maximum frequ-
ency of counted pulses (to eliminate interferences on the
input of the counter);
» Memory of counter status after power failure;
» Digital input.

  • Page 2 Functioning The MB-LI-4 module is a four-channel one-way counter. Each channel is independent and counts the impulses in accordance with individual settings. The results are presented in the form of a Number of pulses and rescaled value in a range from 0 to ~4,29 billion. Reading of the counter can be reset independently for each channel.
  • Page 3 Mounting The use of anti-interference and surge filters (such as OP-230) is recommended. It is recommended to use shielded twisted-pair cables to connect the module to another device. When using shielded cables, ground the screens only on one side and as close to the device as possible. Do not route signal cables in parallel in close proximity to high and medium voltage lines.

    1. Before installing the module, set the selected Modbus com- munication parameters and measurement options. 2. Disconnect the power supply in distribution box. 3. Install the module on the rail. 4. Connect the module power supply to terminals 1-3 as indica- ted.

  • Page 6 Communication settings reset A configuration jumper is available under the module casing. Starting the controller with the jumper closed restores the facto- ry settings of the communication parameters. To do this, remove the casing of the module and put the jumper on both pins. After the reset is done, remove the jumper.

  • Page 7: Communication Parameters

    Security 1. Galvanic isolation between the IN..., COM... contacts and the rest of the circuit (min. 2.5 kV). and the rest of the system (min. 2.5 kV). 2. No galvanic isolation between module power supply and RS- 485 lines. 3. Overcurrent protection for power supply and communication inputs (up to a maximum of 60 V DC) with automatic return function.
