Product Description

The 502-03676-22 is a two-channel serial communication module from Kollmorgen. It is designed for asynchronous serial communications with operator interface devices (OIDs), computers, and other compatible external devices. This model features a diagnostic LED that turns on briefly during diagnostic tests. Its dedicated processor is the 80C186 variant with a processing speed of 8 MHz. The logic side power requirement of this two-channel variant is 420 mA at 5 Volts.

The 502-03676-22 has a physical size of 41 mm x 305 mm x 213 mm. It accomplishes serial communication with the aid of Dual Universal Asynchronous Receiver/Transmitters (DUARTs). External operator devices are linked to this unit via a channel of the DUART using the corresponding interface. The dedicated processor on the 502-03676-22 features FIFO buffers that function as DUARTs. With the aid of the FIFO buffers, the transfer of data between this module and a computer operator interface becomes seamless, with up to 1K buffered input and output data per time.

The 502-03676-22 operates with emissions below Class A limits, as per EN 55011/CISPR 11. It is immune to magnetic fields, electrostatic discharges, fast electrical transients, and RF electromagnetic fields. According to IEC 68-2-27, the shock resistance of this unit is rated at 15g/11 msec. Also, its vibration resistance is rated at 10 – 57 Hz at a constant amplitude of 0.15 mm or 57 – 2000 Hz at an acceleration of 2g. The operating temperature range of the 502-03676-22 is 7 degrees C to 55 degrees C (45^o F – 131^o F). Its storage temperature range is between -40 degrees C to 85 degrees C (-40^o F – 185^o F). The non-condensing humidity rating of this serial communication module is 5 – 95 %.
