The XTA-MRNO-6 is an interposing relay module with six digital inputs and six mechanical relay outputs. It is intended for use with BusWorks XT Series discrete I/O or other digital output modules for the purpose of driving high energy loads. This module serves as an interim digital interface to switch high voltage devices at high currents based on digital logic inputs. Each pair of output contacts are individually isolated.

These modules are very easy to use. Removable front-facing terminal blocks on the module’s top and bottom greatly simplify field wiring. Individidual channel LEDs indicate the output state for convenient troubleshooting.

Rugged construction and high density design combine for a very effective I/O solution. These units are ideal for remote monitoring, distributed control, or SCADA applications.

Input Ranges: 4-32V digital logic (0V OFF, 4-32V ON)
Output Ranges: Relays drive up to 250V AC / 30V DC at 5A
Power Requirement: 12 to 32V DC

Performance Specifications

Digital Inputs (Logic Side)

Configuration: Six DC voltage inputs share return with power
Input Signal Voltage Range: 0 to +32V DC, 36V peak
Input Signal Threshold: 4V DC typical w/100mV hysteresis
Input Impedance: 10KΩ typical, input includes 10KΩ pull-down to return
Input Response Time: See Output Response Time
Input Over-Voltage Protection: Bipolar transient voltage suppression (TVS diodes) and capacitive filtering (0.1µF) is included at every input. TVS diodes are rated for a working voltage up to 38V DC, a breakdown voltage of 72V DC, and a clamping voltage of 100V DC.
Input Current: 3.2 mA at 32V DC, typical. Inputs include 10KΩ pull-downs to return

Relay Outputs (Field Side)

Configuration: Six normally open, isolated, SPST, mechanical relay contacts
Contact Type: 1 Form A (Six Channels), plastic-sealed contacts
Contact Material: Gold overlay silver-Nickel alloy (Au + Ag 90 Ni 10)
Maximum Switching Voltage: Up to 277 V AC or 125V DC, maximum
Maximum Switching Current: 5A maximum
Minimum Load: 1mA, 5V DC
Maximum Switching Power: Up to 1,250VA or 150W, maximum
Contact Resistance: 1000mΩ at 500V DC, minimum (initial contact resistance)
Dielectric Strength: 750V AC (50/60Hz) for 1 minute between open contacts, 3000V AC (50/60Hz) for 1 minute from contacts to input coil.
Mechanical Life: 20 x 106 operations, minimum. External contact protection is required for use with inductive loads.
Electrical Life: 100 x 103 operations, minimum at 3A & 250V AC, 30V DC resistive. 50 x 103 operations, minimum at 5A & 250V AC, 30V DC resistive w/ switching frequency at 20 times/minute.
Note: It is not recommended to switch mechanical relay contacts at high frequencies for long periods of time as this will quickly degrade the life of the relay.
Output Response Time: 5.25ms typical, 10ms maximum, no bounce measured from input trigger to corresponding output contact closure.
Note: External relay contact protection is required for use with inductive loads. Failure to use adequate protection may reduce contact life or damage the unit.
