3. Product Overview
The Space Age SSU-PAM-4 is a multi-voltage, single-pole, double-throw (SPDT) relay module. It features an encapsulated enclosure for durability and includes an LED indicator for status. The relay is supplied with 12-inch (30.48 cm) leads and six wire nuts for connection.
Figure 1: Space Age SSU-PAM-4 Multi-Voltage Series Relay. This image shows the compact, encapsulated black housing of the relay with multiple colored wires (red, black, white, yellow, orange, blue) extending from it. A label on the relay body indicates its model number (AP&C-PAM1), UL listing, and wiring details including voltage ratings (15mA, 10.0AMP @115VAC) and contact configurations (WHT-0V, BLK-115 N.C., RED-24 N.O., C.-BLU, -YEL, -ORG). The wires are #18 AWG, rated 105°C.
Key features include:
- 10.0 A at 120 VAC, 7.0 A at 24 VDC, 250uA at 5 VDC
- Multi-Voltage Relay Module
- SPDT (Single-Pole, Double-Throw) contact configuration
- Encapsulated enclosure
- Integrated LED indicator
4. Setup and Installation
The SSU-PAM-4 relay is designed for panel mounting. It comes with double-sided adhesive tape and a mounting screw for flexible installation options. Ensure the mounting surface is clean, dry, and stable.
4.1 Wiring Instructions
Refer to the wiring diagram on the relay label and the specifications below for correct connections. Use the provided wire nuts for secure electrical connections.
| Function | Wire Color | Description |
|---|---|---|
| Input (Coil) | White (WHT) | 0V (Common for input) |
| Input (Coil) | Black (BLK) | 115V Input |
| Input (Coil) | Red (RED) | 24V Input |
| Common (C) | Blue (BLU) | Common contact for switched circuit |
| Normally Closed (N.C.) | Yellow (YEL) | Contact closed when relay is de-energized |
| Normally Open (N.O.) | Orange (ORG) | Contact open when relay is de-energized |
Important: Connect the appropriate input voltage (115V or 24V) to the Black or Red wire, respectively, with the White wire as the common return. The Blue wire is the common for the switched load. The Yellow wire provides a Normally Closed (N.C.) connection, and the Orange wire provides a Normally Open (N.O.) connection to the Blue common.
5. Operating Instructions
Once properly wired and powered, the SSU-PAM-4 relay operates automatically. When the coil is energized by the input voltage (115V or 24V), the internal contacts switch state:
- The connection between the Blue (Common) and Yellow (Normally Closed) wires will open.
- The connection between the Blue (Common) and Orange (Normally Open) wires will close.
The integrated LED indicator will illuminate when the relay coil is energized, providing visual confirmation of its operational state.
6. Maintenance
The Space Age SSU-PAM-4 relay is designed for minimal maintenance due to its encapsulated enclosure. However, periodic inspection is recommended:
- Visual Inspection: Check for any signs of physical damage, discoloration, or loose connections.
- Connection Integrity: Ensure all wire connections remain secure and free from corrosion.
- Environmental Conditions: Verify that the operating environment remains within the specified temperature and humidity ranges.
No user-serviceable parts are inside the encapsulated enclosure. Do not attempt to open the relay.
7. Troubleshooting
If the relay is not functioning as expected, consider the following troubleshooting steps:
- No LED Indication:
- Check if the correct input voltage (115V or 24V) is applied to the Black or Red wire, respectively, with the White wire as common.
- Verify that power is supplied to the circuit.
- Inspect all wiring for loose connections or breaks.
- Relay Not Switching:
- Confirm the LED indicator is illuminated, indicating the coil is energized.
- Ensure the load connected to the Blue, Yellow, and Orange wires is within the relay's current rating.
- Check the continuity of the switched circuit.
- Slow Response Time:
- While the SSU-PAM-4 is designed for general switching, some applications may require faster response. If a 2-second activation delay is observed and unacceptable for your specific application, consider alternative relay types designed for high-speed switching. This relay is not optimized for instantaneous response in all scenarios.
If issues persist after troubleshooting, contact Space Age technical support.
