ESD Protection

Since the I/O lines are connected to the radar system, there is a potential for lightning or other ESD-type damage.

The following I/O-62 features make RCP resistant to transient surges:

• Wires are protected by a Tranzorb diode, which transitions from an open to a full clamp between ±27 to ±35 VDC. The connector panel also uses Tranzorb diodes on every I/O line for double protection.
• High-voltage tolerant front-end receivers/drivers. All components connected to the external pins can tolerate up to ±40 V. For example, the TTL and wide range inputs use protectors that normally look like 100 Ω resistors, but open at high voltage.
