Operation

The KRCDM10 provides several timed functions in a single device, reducing the need to use separate timer relays for different basic timing operations.

Depending on the selected mode, it can perform activation delays, timed intervals, repetitive cycles, pulses and other control sequences.

The actual configuration of each function must follow the functional diagram and specific instructions for the equipment.

10 Operating Modes

A — ON Delay

Timing starts after the corresponding command or power supply is applied, and the output changes state after the configured period.

B — Interval

Keeps the output activated for a defined time interval following the triggering event established by the circuit.

C — Cyclic Starting OFF

The cycle begins with the output OFF. After the first configured period, the output changes state and starts the corresponding cyclic sequence.

D — Cyclic Starting ON

The cycle begins with the output ON and subsequently alternates states according to the programmed timing periods.

E — OFF Delay

Allows the output to remain activated for a defined period after the control signal is removed, according to the electrical configuration used.

F — Rising-Edge Pulse

Generates a timed pulse when the control signal changes to its active state.

G — Falling-Edge Pulse

Generates a pulse associated with removal or deactivation of the control signal.

H — ON/OFF Pulse Delay

Provides timed operation involving ON and OFF states according to the selected logic.

I — Impulse Relay

Provides output state changes through successive control impulses according to the operating logic of the device.

J — Output Pulse

Generates a timed output pulse according to the triggering condition and configured time.

Dual Cycle Operation

The dual cycle configuration provides two channels, increasing the possibilities for creating timed sequences.

The exact relationship between channels, contacts and available timing settings should be confirmed using the functional diagram for the specific model.

Accuracy

The stated accuracy for the KRCDM10 is ±2%.

For applications where timing is critical, electrical and environmental operating conditions should also be considered.

Timing Range

The unit provides a general timing range from seconds to hours, depending on the selected function and configuration.

Specific limits for each range should be confirmed on the product identification and technical instructions.

Current

The stated current is up to 10 A.

Actual permissible current depends on the characteristics of the controlled load. Resistive, inductive and electronic loads, as well as loads with high starting currents, may behave differently.

When required, the KRCDM10 can be used in a control circuit together with a properly rated contactor or intermediate relay.

DIN Rail Mounting

The KRCDM10 is designed for DIN rail mounting, facilitating integration into control panels with other electrical and automation components.

Operating Temperature

The stated operating temperature range is -10 °C to +55 °C.

The equipment should be installed in an environment compatible with this range and with appropriate ventilation, protection and mounting conditions.

Installation and Safety

Installation should be performed by a qualified professional according to the electrical design and applicable technical standards.

Before energizing, check:

• supply voltage;
• network frequency;
• load characteristics;
• circuit current;
• protective devices;
• electrical connections;
• selected function configuration;
• operating sequence.

For motors, pumps and other power loads, the timer relay should be part of the control logic and should not replace contactors, overcurrent protection, thermal protection or other devices required by the electrical design.
