Product Details
YDOA is compatible with terminal boards
TRLYS1B Relay Output with Coil Sensing：
The Relay Output with coil sensing (TRLYS1B) terminal board accepts 12 relay outputs wired directly to two barrier type terminal blocks. Each block has 24 terminals that accept up to #12 AWG wires.
The first six relay circuits are jumper configurable either for dry, Form-C contact outputs, or to drive external solenoids. A standard 125 V dc or 115/230 V ac source, or an optional 24 V dc source, can be provided for field solenoid power. The next five relays are unpowered isolated Form-C contacts. Output 12 is an isolated Form-C contact, used for special applications requiring dedicated power from connector JG1. TRLYS1B supports a single YDOA on connector JA1, or three YDOAs on connectors JR1, JS1, and JT1. The fuses should be removed for isolated contact applications to ensure that suppression leakage is removed from the power bus.
TRLYS1D Relay Output with Servo Sensing：
The Relay Output with servo sensing (TRLYS1D) terminal board holds six plug-in magnetic relays wired to a barrier type terminal block. The six relay circuits are Form-C contact outputs, powered and fused to drive external solenoids. A standard 24 V dc or 125 V dc source can be used. TRLYS1D supports a single YDOA on connector JA1, or three YDOAs on connectors JR1, JS1, and JT1.
TRLYS#F Relay Output with TMR Contact Voting：
The Relay Output with TMR contact voting (TRLYS1F) terminal board provides 12 contact-voted relay outputs. TRLYS1F holds 12 sealed relays in each TMR section, for a total of 36 relays among three boards. The relay contacts from R, S, and T are combined to form a voted Form A normally open (NO) contact. 24/125 V dc or 115 V ac power can be applied. Three YDOA packs plug into the JR1, JS1, and JT1 37-pin D-type connectors on the terminal board. TRLYS#F does not have power distribution or support simplex systems.
SRLY Simplex Relay Output：
The Simplex Relay Output (SRLY) terminal board provides 12 form C relay contact outputs wired to a Euro-style box terminal block. Each of 12 sealed relays uses an isolated contact set for relay position feedback. The SRLY accepts a single YDOA, which can have one or two network connections.
SRSA Simplex Compact Digital Output：
The Simplex Compact Digital Output (SRSA) terminal board provides 10 relay outputs, grouped as bank A and bank B. Each bank contains 5 outputs as a series combination of force-guided relay contacts and a solid-state relay. The primary disconnect operation should use the solid-state relays. The mechanical relays, one for each bank, are provided for redundancy and safety purposes.
