A2SAM505-H000 S1 Yokogawa Current/Voltage Output Adaptor

Hardware Specifications

Analog Output Signal Conditioning and Electrical Isolation

The A2SAM505-H000 S1 provides configurable analog output interfacing for voltage and current signals. Consequently, the control system can transmit output commands to compatible field devices using the specified signal ranges.

The output characteristics include:

• Voltage mode: 0 to 10 VDC, with an allowable output range of -0.3 to 10.3 VDC.
• Current mode: 4-20 mA DC, with an allowable output range of 1 to 23 mA DC.
• Voltage load: Requires a load resistance of 10 kOhm or higher.
• Current load: Supports 750 Ohm maximum at 20 mA and 600 Ohm maximum at 23 mA.
• Electrical separation: Withstands 1500 VAC between output signals and the system for 1 minute, and 500 VAC between I/O adaptors for 1 minute.

These specifications define the electrical operating limits for the adaptor and its connected output circuits. However, the supplied data does not specify channel count, output accuracy, or conversion resolution.

Field Installation Guidelines

1. Mounting: Install the A2SAM505-H000 S1 on the dedicated A2BN3D Base Plate for Adaptor. Verify mechanical alignment and secure engagement before connecting field wiring.

2. System compatibility: Confirm that the target CENTUM VP N-IO configuration supports the adaptor and the specified A2MMM843 style 2 or later I/O module.

3. Signal configuration: Select the required voltage or current output mode through the applicable system configuration. Verify that the connected field device accepts the selected signal range.

4. Load verification: Check the connected load resistance against the specified limits. For voltage output, maintain at least 10 kOhm. For current output, observe the applicable maximum resistance at the operating current.

5. Wiring: Route analog output conductors separately from high-current power wiring where practical. Use appropriate cable shielding and grounding practices according to the system installation documentation.

6. Power supply: Verify the availability of the specified 24 VDC system supply and 5 VDC internal supply. Account for the maximum stated current consumption when checking the applicable power budget.

7. Electrical isolation: Observe the specified withstand voltage limits during system design and electrical testing. Do not apply insulation test voltages beyond the documented ratings.

8. Commissioning: Before connecting field actuators, verify wiring polarity, output mode, load resistance, and the expected output signal using the approved commissioning procedure.
