Port and Switch

12-bit analog Input / Output (23-point type)

23-point type has 2 analog inputs and 1 analog output as standard. This feature makes it possible for 23-point type to be connected directly with various sensors and actuators without adding any analog input /output modules. Either voltage or current can be selected at each point. 10-point type (EH-D10DRA) has 1 analog input (8-bit) as standard.

Input / Output

[Input: 0-10V or 0-20mA, Output: 0-10V or 0-20mA]

This feature can be applied to a pump system for reservoirs using water level sensors.

Two built-in potentiometers for easy set-up
(except for 10-point and 20/40/64-point type)

Timer constant value can be easily changed using these potentiometers even if you do not have a programming device. Values set by the potentiometers are always reflected in the special internal output. Smoothing is possible for these values.

Potentiometers

[The value of the potentiometer 1 and 2 are stored in WRF03E and WRF03F respectively.] [Smoothing: to average the value that varies with time by dividing the specified value.] [The timer value must be set by a variable in advance.]

With these potentiometers, operation interval can be tuned easily.

Built-in high-speed counter

A high-speed counter is provided as standard eliminating the need for an additional counter module for high-speed applications. 14/23/28-point type with DC input can count up to 1-phase 4 channels.

14/23/28-point type	Max. 10kHz
20/40/64-point type	Max. 100kHz

high-speed counter 1

high-speed counter 2

Select one mode from:

1-ph 4 ch, 2-ph 2 ch, or 2-ph 1 ch + 1-ph 2ch [20/40/64-point]
1-ph 4 ch, 1-ph 2 ch, or 2-ph 1 ch + 1-ph 1ch [14-/23-/28-point]
1-ph 3 ch, 1-ph 2 ch, or 2-ph 1 ch [10-point]

By taking input directly from an external encoder, the position of the object being controlled can be detected.

[The functions that can be used (pulse train, PWM, interruption input, etc.) vary in each mode.]

This feature can be applied to the detection of the position of objects on various assembly, processing, and testing lines.

PWM and pulse train output (MICRO-EH with DC output)

PWM output is provided as standard.

Temperature control and light brightness control are possible by modulating the pulse width.

10/14/23/28-point
up to 2kHz

20/40/64-point
up to 65kHz

Pulsetrain output is also provided as standard.

PWM and pulse train output

Simple positioning control, fine tuning of conveyor's moving distance, etc. are possible by pulse train output with acceleration/deceleration function.

10/14/23/28-point
Max. 5kHz

20/40/64-point
Max. 65kHz

Maximum 176 I/O points

(64-point type x1 + 28-point expansion unit x4)
Up to 4 expansion units can be connected.
(except for 10-point type)
Cable length is up to 2 meters in total.

I/O points

Flash memory for storing user programs

To protect valuable programs from being erased during power failure, the MICRO-EH contains flash memory for storing user programs.

Built-in real-time clock for event scheduling (20/23/28/40/64-point type)

A real-time clock is provided as standard
(20/23/28/40/64-point type) for event scheduling.

Battery for data memory back-up (23/28/64-point type)

An optional battery is mountable for data memory back-up.

Digital filter

Filtering delay time can be adjusted to eliminate chattering. It can be set between 0 and 20 ms in units of 0.5 ms.

Power supply for sensors
(14/20/23/28/40/64-point type and 14/28-point expansion unit)

The 24V terminal at the input terminal block can supply current to external equipment.
