Overview
The Square D 3020-IOM-44 is a PowerLogic I/O (Input/Output) module manufactured by Schneider Electric (formerly Square D) for industrial power monitoring and circuit breaker control. The 3020-IOM-44 has four status IN, one KYZ pulse OUT, and three Form-C relays OUT. The 3020-IOM-44 is not suitable to be used with standard function circuit breakers. However, it will allow a MicroLogic ‘full-function’ circuit breaker unit to communicate and be networked within a Powerlogic network.
Key Features
- Four Status Inputs: Current range 0–7.4 A ac at nominal 5 A ac; voltage range 0-180 VAC at typical nominal 120 VAC.
- KYZ Pulse Output: Solid-state KYZ relay rated 240VAC and 300VDC with maximum rating of 96mA. Designed for pulse initiator applications and best relay used for any pulse applications.
- Three Form-C Mechanical Relays: Form-C 10A mechanical relays with limited life of about 10 million operations under no load or 100,000 operations under a load.
- Alarm Capability: Can detect over 100 alarm conditions, and can have multiple alarm conditions assigned to one relay.
- Time-Stamped Events: Status inputs for date and time are accurate to within one second.
Technical Specifications
- Control Power Input (AC): 100-264 VAC, 47-440 Hz frequency range, 14-19 VA typical burden
- Control Power Input (DC): 100-350 VDC
- Power Burden: 14VA at 120V and 20VA at 240V
- Mounting: Flush mount with four screws, two on each top and bottom of the module.
- Dimensions: 6.0 in x 4.0 in x 3.0 in (15.2 cm x 10.2 cm x 7.6 cm)
- Weight: 1 lbs 9.0 oz (0.7 kg)
- Country of Origin: United States
Typical Applications
The Square D 3020-IOM-44 is suited for industrial and commercial power distribution systems requiring expanded I/O functionality:
- Alarm notification and relay control in PowerLogic circuit breaker networks
- KYZ pulse output for energy meter data collection and telemetry
- Setpoint-controlled relay operation for non-time-critical protection and switching
- Integration with MicroLogic full-function circuit breakers in networked monitoring systems
- Industrial automation systems requiring status input monitoring and multi-condition alarm routing
