Relay Outputs
EKE 1A has 1 relay output:
• Type SPDT relay. Digital Output can be used to connect either a solenoid valve or an alarm.
• The relays cannot be used for the direct connection of capacitive loads such as LEDs and ON/OFF control of
EC motors. All loads with a switch-mode power supply must be connected with a suitable contactor or similar.
Cable length
EKE controller supports the following max. cable length.
Analog inputs (Voltage)
Temperature sensor
Stepper valve connection
Power supply
Digital input
Digital output
Digital MMI
Cable and wiring *)
•
The max. cable distance between the controller and the valve depends on many factors like shielded/
unshielded cable, the wire size used in the cable, the output power for the controller and EMC.
•
Keep controller and sensor wiring well separated from mains wiring.
•
Connecting sensors by wires more than the speci ed length may decrease the accuracy of measured values.
Warning
Separate the sensor and digital input cables as much as possible (at least 10 cm) from the power cables to the loads to
avoid possible electromagnetic disturbance. Never lay power cables and probe cables in the same conduits
(including those in the electrical panels).
