General Specifications; Block Diagram - Siemens SITRANS RD500 Operating Instructions Manual

GENERAL SPECIFICATIONS

1. POWER: Derived from system backplane. (The module draws 170 mA max. load on
power input of RD500). Modules may be hot-swapped (replaced while powered
up).
2. LEDs:
STS - Status LED shows module condition.
IN1-IN8 - LEDs are lit when associated input is active.
ALM - Alarm LED is lit when an internal alarm condition exists.
3. MEMORY: Non-volatile memory retains all programmable parameters. RD500
also stores the parameters in order to reprogram modules that are replaced.
4. INPUTS: DIP switch selectable for sink or source
Maximum voltage: +30 VDC, reverse polarity protected
Off Voltage: < 1.2 Volts
On Voltage: > 3.8 Volts
Input Impedance: Source Mode 10K ohms; Sink Mode 20K ohms
Input Frequency*:
Filter switch on: 50 Hz
Filter switch off: 300 Hz
* Actual useable frequency limited by communication to external device.
5. OUTPUTS:
Form A Relay Output:
Type: N.O.
The following pairs of relays share the common terminal: 1&2, 3&4, 5&6
Current Rating by pair: 3 Amps @ 30 VDC / 125 VAC resistive
1/10 HP @ 125 VAC
Life Expectancy: 200,000 cycles at maximum load rating. (Decreasing load,
increasing cycle time, and use of surge suppression such as RC snubbers
increases life expectancy.)
6. ISOLATION LEVEL: 500 Vrms @ 50/60 Hz for 1 minute between the following:
Inputs
Outputs
RD500 Power Supply Input
7. COMMUNICATIONS: Provided by the RD500
8. ENVIRONMENTAL CONDITIONS:
Operating Temperature Range: 0 to +50°C
Storage Temperature Range: -40 to +85°C
Operating and Storage Humidity: 85% max relative humidity, non-condensing,
from 0 to +50°C
Vibration According to IEC 68-2-6: Operational 10 to 150 Hz, 0.075 mm
amplitude in X, Y, Z direction 1 g.
Shock According to IEC 68-2-27: Operational 25 g's (10 g's relay), 11 msec in 3
directions.
Altitude: Up to 2000 meters
