How much does an energy management system cost in Pakistan?
What drives the cost of an industrial energy management system in Pakistan, what to ask suppliers, and how to start small without overspending.
The ES-IGW-E1 reads sensors directly on its analog and digital inputs, controls equipment through its relay outputs, and talks to meters and controllers over Modbus, RS485, RS232 and CAN bus. You configure it from a web dashboard.

| Ethernet | 2x (Internet + Modbus TCP) |
|---|---|
| Serial | 1x RS485, 1x RS232 |
| Fieldbus | CAN bus |
| Analog inputs | 4x (0–20 mA / 0–10 V, 16-bit) |
| Digital inputs | 8x (12–24 V) |
| Relay outputs | 8x, for actuator control |
| Power | 24V DC / 10A |

Wire temperature, pressure, flow or humidity transmitters with 0–20 mA or 0–10 V outputs straight into its four 16-bit analog inputs.
Pick up running, fault or mains-failure signals on eight 12–24 V digital inputs.
Switch actuators such as pumps, fans or alarm sounders through eight relay outputs.
Combine Modbus TCP and RTU, RS232 and CAN bus devices with direct sensors, at sites where equipment comes from many vendors.
HVAC, cleanroom utilities and compressed air monitoring for compliance and uptime.
Machine health on looms and spinning lines, plus energy per production unit.
Boiler, chiller and compressed-air monitoring, plus production line uptime.
Pump, motor and utility monitoring for continuous processes.
Mains, generator, fuel and DC power monitoring, plus panel alarms, across distributed sites.
Temperature monitoring, compressor health and instant alerts on power loss.
Multi-meter energy tracking, plus HVAC and generator costs per floor or tenant.
Line uptime, motor and VFD health, and compressed air leak detection.

Any sensor with a 0–20 mA or 0–10 V output on the four 16-bit analog inputs, and 12–24 V signals on the eight digital inputs.
Yes. Eight relay outputs switch actuators such as pumps, fans or alarm sounders.
24V DC at 10A.
Yes. It has the same two Ethernet ports (internet and Modbus TCP) and RS485, plus RS232 and CAN bus.
