OC950-604-01

OC950-604-01 is a Pacific Scientific component in the OC950 Option Cards series. Its PacLAN network interface supports controller communication at a data rate of 2.5 MBaud. The network can accommodate a cluster of up to 255 controllers, with a maximum of eight stations on each segment. PacLAN connections use RG62U coaxial cable with 93 Ω termination, and the bus can extend up to 305 m.

The serial interface supports RS-232 and RS-485 communication, with selectable baud rates of 19,200 or 9,600. The card provides 21 programmable, bidirectional I/O channels for receiving input signals or controlling outputs. These channels operate with logic voltages from 5 to 24 V and have an output sink capability of 100 mA.

The user supply requires 5 VDC with a tolerance of ±5% and draws no more than 200 mA. The card also includes 128K × 8 NVRAM for retaining stored data without continuous power. Its NVRAM data-retention period is 10 years.
