  • terminals
  • 19" rack mount housing kit

Preparation for work

  • Remove the top cover of the housing
  • Connect the backup power module to the controller
  • Install rack mounts
  • Install the top cover of the housing, tighten the screws included in the kit

Power Supply

External power supply

The permissible power range is 5-22V. The average consumption of the device is 1.5-2 watts. But since the GSM module consumes up to 8W impulsively, it is recommended to use power supplies with a power of at least 10W.


The power connector for the standard jack 5.5x2.1mm is located on the front panel.

Power over Ethernet

Power-over-Ethernet (Passive PoE) is supported via RJ45 connector on the front panel. Supports the standard voltage of 12V and 15V. See Power over Ethernet/en.

Battery

The Wiren Board NETMON-2 can be equipped with one or two Li-Ion (Li-Pol) batteries with a maximum voltage of 4.2 V. When the power is connected, the battery is charged with a current of up to 0.5 A.

There is protection against charging at low temperatures and overheating.

GSM/GPRS-modem

The GSM antenna is connected to the SMA connector on the front panel of the controller. If the GSM signal is weak, it is recommended to use a remote antenna and place it away from the controller.

USB port

Wiren Board NETMON-2 has one USB port (Host, type A) inside the case. The port is designed to connect Wi-Fi sticks, 3G modems, etc.

External load switching

The relay outputs on the front panel

There are four groups of relay outputs, output on the connector terminals, on the front panel of the Wiren Board NETMON-2.

SPST contact configuration (two contacts per relay: NO/COM).

Current up to 10A per channel. The module has protection against sparking of the contacts.

Parameter Value
Number of outputs 4
Output type mechanical relay
Contact configuration SPST, normally open

conditions:

off,

K and NO are closed

Maximum switching voltage, AC 250V
Maximum switching voltage, DC 30V
Maximum switching current, per channel (*) 10A
The channel resistance in the open state < 100 mOhm
Voltage isolation between the controller and the output 1500Vrms
Lifetime: number of switches

for load 10A 230V AC, cos φ = 1

100 000

*) Maximum switching current is specified for 230V AC resistive load.

Relays are connected in a phase break.

connection diagram

Digital inputs

Purpose

Connection of pulse counters, buttons, switches, sensors with "dry contact"output.

Technical parameters

8 inputs for connection of "dry contacts" with group galvanic isolation. The scheme of inputs is shown in the figure. The terminal is supplied ~ 4.5 V, when the earth current flows a small (1mA), causing the operation of the input.

Parameter Value
Number of inputs 8
Isolated input groups 1
Input type "dry contact",

the opening of the current at

earth short

Operation condition GND input lockout
Tripping current 1 mA
Minimum pulse width to trigger 10 ms
Minimum time between consecutive signals 5 ms
Voltage of "wetting" 4.5 V

Connection

Sensors/counters with pulse outputs/buttons.

Such devices form a signal by closing two wires that are suitable for them. Connect one wire to the GND terminal of the module. Connect the second wire to the Dx terminal. Some counters have a pulse output on the optocoupler, then the two wires have a polarity - "plus" and "minus". In this case, minus is connected to GND, plus to Dx.

Devices with open collector output.

The device and the module must have a common ground. Connect the open collector output to the Dx terminal.

The module inputs are galvanically isolated from the controller. Therefore, the ground GND of the module and the controller may be different.
