ETA-ECS6RM SEQUENCER CONTROLLER INTERFACE WITH ETA-20SH
To get maximum use of the ETA-20SH we suggest using the ETA-ECS6RM controller. When the two are interfaced the ETA-ECS6RM
controller not only can remotely turn on the ETA-20SH but it can monitor the AC Mains Voltage and Current of the ETA-20SH. When
mated, the microprocessor in the ETA-ECS6RM can determine if there are any potentially damaging AC Voltages present at the ETA-
20SH and shut it off before damage can occur to sensitive equipment connected.
1. ECM Control Ports –
Up to 6 AC Main circuits can be activated or monitored by the ETA-ECS6RM. Each ECM control port
connects to one of the following ECM modules: ETA-ECM20M, ETA-15SH, ETA-20SH, or the ETA-ECM20. For connection
between the ETA-ECS6RM and an ECM module, use a 5 conductor cable that is a minimum of 22-gauge wire. We suggest
using CAT5 cable due to the common availability. Pay special attention to the port connections and DO NOT MISS WIRE or
damage may occur. The distance between the ETA-ECS6RM and an ECM module can be up to 1000'.

2. Relay Contacts –
Each Channel of the ETA-ECS6RM also has a Relay contact that works in conjunction with the ECM control
port. Sequencing and timing of these connections are the same as the corresponding ECM channels. Example: Sequence 1
ECM Port output works at the same times CH 1 Relay contact.
Note: All ECM modules can be triggered using the Relay contacts to activate the ECM module.
