17.6.2 Synergy Nano Plus Retransmit Outputs

Wire retransmit outputs to the chart recorder or control valves as necessary. Use 4-20 mA converters as

required. See Section 6.4 Special Functions

for setup details. The following table displays the connector

and pin numbers for the Synergy Nano’s two analog retransmit outputs. Below the table is an image of the

Olympic Board connector P4, pins 9-12.

17.6.3 Synergy Nano Plus Triac Outputs

Synergy Nano output boards are multi-channel Triac controlled solid state relays that control the

environmental test chamber’s the heaters compressors, blowers and solenoids. These outputs handle small

to medium current AC loads directly. The Synergy Nano output boards are also designed to drive external

Triacs for larger outputs such as compressors and heaters. In addition, to driver larger loads, the Triac

outputs can operate intermediary mechanical and solid state relays.

The figure below shows three output configurations for a triac board: These are:

1. Drive an external Triac to control an AC motor load. When an external Triac is driven, an additional

QuenchArc snubber (resistor capacitor) network is required across the Triac input to prevent

nuisance firing as a result dV/dT switching noise.

2. Drive a small solenoid load directly.

3. Drive a Solid State Relay (SSR) module. When driving an SSR, an additional load resistor is

required across the SSR input to prevent nuisance firing as a result of leakage current.
