Product specification
I-CODE Long range reader
module hardware
SLRM900
7.5
EMC and EMI
The SLRM900 is designed in such a way that it is possible
to build systems with it, which are in conformance with
EMC and EMI standards.
Electromagnetic emissions comply with the guidelines in
BAPT 222 ZV 122 and EN 300 330. Electromagnetic
immunity complies with the guidelines in ETS 300 683.
The conformance to EMC and EMI standards can only be
granted for systems, not for components.
The following measurements have been passed:
EMI: EN 300 330, BAPT 222 ZV 122, FCC 47 part 15
Immunity: ETS 300 683.
The following configuration is in compliance with the
telecommunication standards:
SLRM900: output power 4 W at 50
; modulation index
m = 15%; standard mode
Linearpowersupply(accordingtotherecommendations
in Table 1), connected via the supplied power supply
cable
Antenna from the I-CODE evaluation kit:
– size: 38 cm
×
28 cm
– number of turns: N = 1
– quality factor: Q = 30
– impedance:
Z

– according to application note "I-CODE, Design of
Read/Write antennas"

Safety and reliability considerations
The SLRM900 has implemented measures for high
reliability.
7.6.1
A
NTENNA RUPTURE AND ANTENNA SHORT
-
CIRCUIT
The SLRM900 does not immediately get damaged in case
of either an antenna short-circuit, or an antenna rupture
with short duration. However, permanent antenna
short-circuit, or antenna rupture, will definitely damage the
SLRM900. The supply current of the SLRM900 will be
limited at typical 1.6 A.
7.6.2
S
UPPLY VOLTAGE
The SLRM900 is protected against short supply voltage
peaks and incorrect polarity for a short time, but
permanent incorrect supply will definitely damage the
device.
