RDAG12-8 产品技术规格
Analog Outputs

● Channels: Eight independent.

● Type: 12 bits, double-buffered.

● Non-linearity: ±0.9 LSB maximum.

● Output Ranges: 0-5V, 0-10V, ±5V.

● Current Output: 4-20mA (user supplied 5.5-28V).

● Output Drive: up to 10mA maximum.

● Drive Capability:RDAG12-8H: 250mA outputs.

● Output Resistance: 0.5Ω.

● Monotonicity: ±½ bit.

● Settling Time: 15usec to ±½LSB for full-scale change of output.

Digital I/O

● Number of Bits: Seven parallel bits. Each is software configured to be input or output on a bit-by-bit basis.

● INPUT:Logic Low: -30.0 to +0.8 VDC at -0.4 mA max. Protected to -140VDC

● INPUT:Logic High: 2.0 to 50.0 VDC (20uA max at 5V in, 5mA max at 50V in)

● OUTPUT:Logic-Low Sink Current: 350 mA maximum. Inductive-kick suppression diode included in each circuit.

● OUTPUT:High-Level Output Voltage: Open collector, compliance with up to 50V user-supplied voltage. If no user-supplied voltage exists, outputs are pulled up to +5VDC via 10 kilohm resistors.

Environmental

● RDAG12-8

- Operating Temperature Range: 0° to 65°C. (Optional -40°C to +80°C.)

- Storage Temperature Range: -20°C to +70°C.

● RDAG12-8H

- Operating Temperature Range:0° to 65°C. (Optional -40°C to +80°C.)

- Storage Temperature Range: -20°C to +70°C.

● Humidity: 5% to 95% RH, non-condensing. Enclosure is designed to meet NEMA 4 requirements.

Power Required

● Power for the opto-isolated section can be applied from the computer’s +12 VDC power supply via the serial communications cable, if a four-wire cable is used, or by a local isolated power supply. Power for the rest of the pod can be provided by a local power supply.

● Opto-Isolated Section: 7.5 to 28 VDC @ 40 mA maximum (7 mA at 12 VDC .)

● Local Power

● RDAG12-8:7.5 to 16 VDC at 400 mA (typical).

● RDAG12-8H:7.5 to 16VDC @ 2.3A

Regulatory Compliance

● This product is designed to be in full compliance with CE requirements.
