ETA-ECS6RMSEQUENCERCONTROLLERINTERFACEWITHETA-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. ECMControlPorts–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
usingCAT5cableduetothecommonavailability.PayspecialattentiontotheportconnectionsandDONOTMISSWIREor
damage may occur. The distance between the ETA-ECS6RM and an ECM module can be up to 1000'.

2. RelayContacts–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
