Product catalog summary

Overview: The document outlines the technical specifications and operational guidelines for the Digital Control Relay MCU-10, used in various applications such as temperature monitoring with RTDs, thermistors, and thermocouples. It also covers other models like MXC-10, MXC-20, MXC-30, and MXV-30, designed for monitoring single-phase and three-phase currents and voltages.

Mounting Options: The MCU-10 relay can be mounted using an 11-pole plug-in or directly on a DIN rail, allowing for flexible integration into different systems.

Output Relay: Features a Single Pole Double Throw (SPDT) relay with a maximum load of 8A/240V AC and a minimum of 10mA/24VDC, supporting up to 1000 operations per hour at maximum load.

Supply Voltage: Supports a wide range of supply voltages from 12-48V DC, 12-30V AC, to higher AC voltages up to 380/415V AC, making it versatile for various power systems.

Input Specifications: Capable of measuring DC and AC currents and temperatures using RTDs and thermocouples with a 1% full-scale accuracy.

Display and Controls: Equipped with a 3½-digit LCD display for real-time monitoring and setpoint adjustments, updating every 0.4 seconds. Adjustments are made using a front-mounted potentiometer.

Operational Modes: Configurable to energize the output relay above or below a setpoint, with a hysteresis of 1% of the full range to prevent frequent switching.

Protection and Compliance: Conforms to EMC standards EN 50081-2/EN 50082-1, providing isolation up to 4kV AC for AC versions. It is housed in a protective casing with IP40 or IP20 protection, depending on the mounting type.

Applications: Suitable for general process instrumentation and signal monitoring, with the ability to scale outputs to engineering units for precise control and monitoring.

Technical Specifications: Includes measuring ranges for DC signals, input impedance, temperature drift, display features, output relay specifications, supply voltage options, and protection ratings.

Configuration and Calibration: User-adjustable within scale limits of -1999 to 1999 with a maximum span of 2000 steps. Provides a guide for calibrating the control relay using a 4-20mA input signal.

Single Phase Voltage Relay (MXV-10): Designed for detecting AC/DC over-or under-voltage with adjustable setpoint and hysteresis, automatic locking function, and inversion of relay function.

Single Phase Current Relay (MXC-10): Monitors AC or DC current with adjustable setpoint and hysteresis, automatic locking function, and inversion of relay function.

General Specifications: Designed according to standards such as EN60204-1, VDE0110, IEC664, and EN61010 for electrical safety and EMC compliance. CE-marked with protection ratings and specific mounting and terminal configurations.

Mechanical Dimensions and Technical Data: Provides specifications for MXL-10 and MXT-10 thermostat relays, including size, weight, input sensitivity, probe voltage and current, temperature drift, hysteresis, reaction time, and probe cable specifications.

Operation and Features: MXT-10 thermostat relay is used for temperature monitoring and control within a range of -50 to 300°C, featuring a Pt100 probe input, adjustable setpoint and hysteresis, and LED indicators for status updates.

Wiring and General Data: Includes wiring diagrams for MXL-10 and MXT-10, detailing connections for AC and DC supply, input, and output terminals, along with general data on ambient and storage temperature ranges, mounting specifications, and protection ratings.
